Classic misdirection, just as a magician would use to fool the crowd.
Everybody gets wound up about fonts, proportional spacing, superscripts, etc., and then Rather yanks the rug out from under us, and says, "yeah, well that doesn't matter, because the ORIGINALS were handwritten, those things you are calling forgeries were just WP versions of the originals, to make it easier to read them.... thus all the forgery claims are now moot, and the original handwritten documents prove Bush lied..."
I still don't see the point. What do they gain by "misdirection"?
Then they'd have to produce the originals.
Your theory only works if CBS had told us, up front, that the originals were handwritten.
Pulling that out of the hat now looks like a shell game, and CBS would look even slimier than it does now.
Although I find it intriguing, I don't buy your theory on this, as I don't see where the facts support it. However, in this dirty world we live in, there's nothing, absolutely nothing would surprise me. The worst mistake that any investigator can make, is to get tunnel vision and lose objectivity.
Here's my conspiracy theory:
This was all cooked up by Microsoft to drum up MS Word sales.
[Okay, so the theory needs a little work...]
